7 breakthrough acoustical products for green buildings

March 01, 2009 |

For all the praise green buildings receive these days, many of these projects fall woefully short of expectations when it comes to acoustical performance. Why?

In many cases, acoustical performance is an afterthought on green projects because some green building rating systems, such as LEED, do not require acoustical credits, says green acoustics guru Jeffrey Fullerton, director of architectural acoustics with Cambridge, Mass.-based consultant Acentech.

Another reason is the minimalist design approach applied on many of these projects: Green buildings tend to have fewer interior walls, higher ceilings, minimal finishes, and hard surfaces.

Ecophon Focus C direct-applied ceiling tiles. “A high-density fiberglass tile that can be used in a glue-up application in existing spaces where lowering the ceiling height is not possible,” says Fullerton. CertainTeed,www.certainteed.com/products/ceilings

Fiber-free, micro-slotted acrylic sound absorbers. “These products are ideal for sound absorption in spaces that might be using radiant heating/cooling systems. Because they don't use fiberglass or porous materials for sound absorption, they eliminate many of the concerns that those materials present. For use in ceiling or wall applications.” DeAmp,www.deamp.com

Tierra rapidly renewable ceiling tiles.“The industry's first biobased, rapidly renewable ceiling tile. For use in open-plan offices where very good sound absorption is sought.” Armstrong,www.armstrong.com/commceilingsna

Echo Eliminator sound absorbing panels. “For use on walls or ceilings. You can use the panel as is or cover it with a stretch fabric for a more finished look. Ideal for conference rooms or video conference rooms where teleconferencing, audio recording, or microphones are used.” Acoustical Surfaces,www.acousticalsurfaces.com

K-13 Spray-on acoustical finish. “For use primarily on ceiling surfaces to provide direct-applied sound absorption to an exposed structural deck in an occupied space.” International Cellulose,www.internationalcellulose.com
